Results of first runs at track

[Moparict]

8psi, E85 and pig rich.  Shifting at 8K in first second and third.  Shifting at 11K in fourth and fifth.  Foot shifting and leaving soft, bike went 9.44 @ 163mph.   124 at the 1/8th.  I have the secondaries pretty close, but the motor is waaaaaaay too rich off boost. 

I was hell bent on not melting anything so I took the Boost by Smith ECU editor and added 10% to the motor map.  It showed too as the bike would spit and sputter until the turbo spooled up.  The datalogs showed an AFR of 10.05-10.10 through the whole RPM range, until the turbo spooled then it leaned out somewhat to 10.4-ish.  So, I didn't melt anything!!  YEA!!!

I am going to put it on the dyno to get the bike dialed in, which I should have done first, but I couldn't help it.  More results to follow.

I will say this.  E85 appears to be very forgiving in the fact that you can run it incredibly rich and the bike will still run pretty clean.  It wasn't until I added the fuel to the motor map that the bike started to run rough off boost.  I'm convinced that if I put the motor map back the way it was, the bike would actually be pretty close to spot on.

Cool! Glad it went well!

I went to the track for the first time with the new turbo yesterday and just on spring pressure(8#) I went 9.02@160 with a shitty 1.57 60"  I cant wait until I get my boost controller so I can turn up the boost. Today I was playing with a manual boost controller on the street and damn they are touchy, I turned it up too much and at 22psi it was violent after I got it settled in at 16psi it was a blast, just like when I first put the stage 1 on it except 4th gear wheelies at 70mph

is that 10.4 with your O2 sensor still set to gasoline?
I claim to be no tuner nor E85 guru, but have read the following online etc.

Gasoline Stoich:  14.7:1
E85 Stoich:  9.7:1

11.8:1 (popular number to shoot for on a turbo bike with gasoline) / 14.7:1 = Lamba of 0.80

To get same lambda ratio on E85 would be something like 0.80 X 9.7 = 7.8:1 if you have changed the fuel type in the logger setup.

Just want to make sure you have not messed with the O2 sensor fuel type on the logger.

The o2 sensor is really measuring residual oxygen anyway and jsut converting teh lambda vales to an engineering value (AFR). Greg is correct in teh different values, but if youleave the o2 sensor alone and shoot for approximately the same "number" as you woudl with gasoline, it will result in ~ the same lambda.

yep, just wanna make sure that is what is happening, i know it is, but just making extra extra sure, hate to see melted pistons etc.

E85 also wants to run a bit richer for peak hp.  I am actually going to shoot for 11.0 just to be safe.  At 10.1 it was spitting and sputtering pretty bad below boost.  I've been told to shoot for 11.6 even on E85, the "same number" thing, but I don't want to melt anything like I did last year.
